Property Type 1DStandards 2D Standards Description
multiScanInt
Metric 1D Readability The multi-scan
integrity. Multi-scan
integrity is a general
measure of the ease
of decoding a symbol
by using multiple
scans across the
barcode. This metric
is a way of measuring
how advanced
decoders might
perform in decoding a
particular barcode. A
low multiScanInt
metric may indicate
many different
problems, as it is a
general measure of
code quality.
signalToNoiseRatio
Metric SEMIT10 (DataMatrix) Signal To Noise Ratio
(SNR) is a relative
measure of the
Symbol Contrast to
the maximum
deviation in light or
dark grayscale levels
in the symbol (ie.
noise).
horizontalMarkGrowth
Metric SEMIT10 (DataMatrix) Horizontal Mark
Growth is the tracking
of the tendency to
over or under mark
the symbol, that is, a
horizontal size
comparison between
the actual marked
cells vs. their nominal
size.
verticalMarkGrowth
Metric SEMIT10 (DataMatrix) Vertical Mark Growth
is the tracking of the
tendency to over or
under mark the
symbol, that is, a
vertical size
comparison between
the actual marked
cells vs. their nominal
size.
dataMatrixCellWidth
Metric SEMIT10 (DataMatrix) Data Matrix Cell Width
is the average width
of each cell in the
matrix (in pixels).
dataMatrixCellHeight
Metric SEMIT10 (DataMatrix) Data Matrix Cell
Height is the average
height of each cell in
the matrix (in pixels).
